This is just the start of what promises to be a really ground-breaking year of user experience with e-content. In fact, I think we may have to stop calling them e-books. I knew that the iPad would be a game-changing device because of its ability to connect content with video and touch as well as connectivity, but to see its ability to utterly transform content is AMAZING.

I know we're going to see more of this when the Microsoft Courier makes a debut, and as soon as the Asus eee Pad comes on sale later this year the market will be blown wide open. Just as the touchscreen smartphone became the norm in a little over 2 years, it will take even less time for tablets and "pads" to do the same.

But what else will be transformed? The evaluation of this content is going to be paramount for consumers - a traditional book or media review is not even going to start to cut it for interim consumers stuck between now, where we are in a real Wild West stage of development and innovation and the future, where (hopefully) standards for e-content will emerge... in some way or another. The same e-content could look radically different on one device than it does on another, and lose or gain functionality when ported to yet another.

I've said in the past that digital content needs to be device agnostic, and I'm willing to stick to that as an ideal for now. But things are getting very interesting, and it is nearly impossible to deny at this point that the publishing, reviewing, and bookstore/library industries are getting ready to pass through a fundamental change. Will consumers who bought a Nook only three months ago be satisfied once they see what their money could have bought in Apple's iPad bookstore? Can Kindle fanatics reconcile themselves to plain black and white e-ink when interactivity and animations are available on new-style tablets?
